Maria Sharapova hasn't been too keen on letting the press into her relationship with fellow pro Grigor Dimitrov, but in a surprisingly open interview with USA Today, she uncharacteristically gushes about Dimitrov -- and says dating a younger man (Dimitrov is 22 years old) is "refreshing."

As for what she's looking for in a man, she says: "It's about finding the person where you can be yourself all the time, where you're comfortable with being younger girl, the older girl, the mature girl, and the person that understands you and look at you and say you're completely off your rocker!

"I have so many things going on in my life and I really love them. Of course I want someone to be by my side to enjoy them. You know, I can jump on a plane tomorrow and go somewhere because I want to do it. And it's really important that that person respects me for the decisions that I make and the things that I do in my life."

She did not, however, offer any of her tips about outrunning the paparazzi.

The two were first spotted cozying up on a Madrid street earlier this month. Sharapova ended her engagement to basketball player Sasha Vujacic last year.
